It can be widely used as a device in urban sewage treatment, water supply industry, power plant inlet, and also as a production process equipment in industries such as textile, food processing, papermaking, leather, etc. It is currently the solid-liquid separation equipment introduced in China.

Product Details

FHG typeReverse fishing grille cleaning machineIt is a device that can continuously and automatically remove various shapes of debris from fluids, with the aim of solid-liquid separation. It can be widely used as a device in urban sewage treatment, water supply industry, power plant inlet, and also as a production process equipment in industries such as textile, food processing, papermaking, leather, etc. It is currently the solid-liquid separation equipment introduced in China.

The advantages of this device are high degree of automation, high separation efficiency, low power consumption, no noise, good corrosion resistance, and can ensure continuous and stable operation without supervision. An overload safety protection device has been installed, which will generate sound and light alarms and automatically shut down in case of equipment failure, thus preventing the equipment from working under overload.

This device can adjust the operating interval of the device according to user needs, achieving periodic operation; It can be automatically controlled based on the liquid level difference before and after the grille; And it has manual control function for easy maintenance. Users can choose freely according to different job needs.

Due to the reasonable structural design of the device, it has strong self-cleaning ability during operation and will not cause blockage, so the daily maintenance workload is minimal.

The equipment specifications are divided into HG300-1500 types according to the machine width size. If the machine width exceeds 1500mm, it will be made into a parallel unit. The grid gap is divided into various specifications such as 1mm, 3mm, 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, etc. The grid gap is selected based on the water flow rate, lifting height, total solid-liquid separation amount, and the shape and particle size of the separated material. Rake teeth made of materials such as ABS engineering plastic, nylon, and stainless steel can be selected according to user needs; The main frame is made of stainless steel material and carbon steel anti-corrosion material.

【FHG typeReverse fishing grille cleaning machineStructure and Working Principle
The rotary grille is mainly composed of a driving device, a rake tooth mechanism, a cleaning mechanism, etc. It is assembled into a set of rotary grille chains by a type of rake tooth. Driven by the motor reducer, the rake chain rotates in the opposite direction of water flow.

When the rake chain is moved to the upper part of the equipment, due to the guidance of the groove wheel and curved rail, relative self-cleaning motion occurs between each set of rake teeth, and the vast majority of solid materials fall down by gravity. The other part relies on the reverse movement of the cleaner to clean up the debris stuck to the rake teeth.

According to the direction of water flow, the rake chain is similar to a grille, and the clearance between the rake teeth assembled on the rake chain shaft can be selected according to the usage conditions. When the rake teeth separate solid suspended solids in the fluid, it can ensure smooth flow of water. The entire work process can be continuous or intermittent.
